Suppliers
Nitrogen, gaseous, <= 10 ppm O2, 8 barg 100 %
Consumption
Pipeline nitrogen is used next to the plant that makes it and is not traded across borders in the packaged data, so consumption equals production.

distribution pipeline5 kmassumedASSUMED over-the-fence pipeline to a consumer on a neighbouring site, reached at the plant's delivery pressure (8 barg) without recompression; the compression is in the plant dataset (GAN compressor).
loss pipeline-leakage0 kg/kgassumedASSUMED no leakage from a welded industrial-gas pipeline: no open source with a leakage rate was found, so none is counted until one is cited.

Not exported:

  • distribution:pipeline 5 km: no background activity (driven by the producer's delivery pressure; pipeline infrastructure outside the market)
  • loss:pipeline-leakage 0 kilogram per kilogram released as N2 (an atmospheric constituent, as lci/mappings.yaml pass_through: no burden, not exported)

Outside the market:

  • Pipeline infrastructure (construction of the line): not counted, as no background activity for it is curated.

How to use it

Downloads

A file with this activity alone is not available: each file above is the whole database, and the line under it says how to find this activity there.

import bw2data as bd
from cheme_as_code_lci import install

bd.projects.set_current("my-project")   # holds your licensed background + biosphere3
install("cheme-as-code-atlas-preview-c3ab348.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-c3ab348", "market:nitrogen/gan-8barg-10ppm:RER"))

While any exchange of the database has no mapping, install() writes nothing and only lists the unlinked exchanges. So the last line finds no activity until the gaps are mapped: the download section gives the ways to use the database now.
